When I was young my regular doctor always did exams by having the nurse tell me to get into underwear. While laying on my back after the abdominal exam, he would pull up and then out and down the elastic of my white briefs and then check for descended testicles and development.
But the one, over the top (traumatic?) exam was (as I have mentioned in other posts) when I was 12 at an unknown doctor for a sore throat etc. and I was fully clothed. He asked me to lay down and he unbuckled my belt, opened my pants, lowered them and my underwear....HE did it for me...without asking....it felt very pervy.
As an adult my doctor asked me to lower my pants and underwear when he needs access.
When doctors use their power...they do as THEY wish.....it is what it is!
